Restoring a Black Plastic Bumper–Part 3

        It’s been almost a month since I posted Part 2, a month where the car has sat out in the weather full time, though the bumper has been protected from direct sunlight by the body of the car itself. That really hasn’t protected the shoe polish. The bumper is back nearly to the same shade of grey it was before I started, though you can easily see where the applicator overlapped the polish during the initial step. If anything, it looks worse now than it does in the photo in Part 2. Well, I expected it.

        I’m going to give it some more time to fade, then try something that can be applied more evenly. Since I’m experimenting with techniques other than commercial car care products in an effort to save money (yeah, right. I’m saving money by trying so many different things) my next step will be something like the Kiwi paste black with included foam applicator. For neatness’ sake I’ll probably need to use some painter’s tape and mask off the bumper from the body panels. I’ve already got some of what I need, but I’ll have to go to the store and get the shoe polish. At the least I expect it to look better than the liquid, but I don’t expect any more durability.

        I’ve done a little reading on the matter, and I really love the guy who used peanut butter to blacken his faded bumper. It’s a neat idea, but all he did was soak the bumper in peanut oil. This darkens it beautifully, but being an organic oil, I wonder both at its durability and long-term effect on plastics. Well, when I get to that point, I’ll let you know. Hmmm… now that I think of it, I wonder what liquid silicone would do on it? I think I’ve got a bottle of that floating around the house somewhere.
